El presente artículo describe los resultados de diseminación participativa de semillas (DPS) en términos productivos, ambientales y socioeconómicos en Cuba y México. El concepto de diseminación participativa de semillas (DPS) surgió en Cuba a partir de la integración de las ferias de diversidad de semillas con la experimentación y diseminación de semillas por los campesinos. Una feria de diversidad de semillas es un método donde los fitomejoradores, productores y agentes extensionistas tienen acceso a la diversidad en uno o más cultivos.
The globalisation of agrifood systems is a mega-trend with potentially profound nutritional implications. This paper describes various facets of this globalisation process and reviews studies on nutritional effects with a particular focus on developing countries. Results show that global trade and technological change in agriculture have substantially improved food security in recent decades, although intensified production systems have also contributed to environmental problems in some regions.
Objective
The association between farm production diversity and dietary diversity in rural smallholder households was recently analysed. Most existing studies build on household-level dietary diversity indicators calculated from 7d food consumption recalls. Herein, this association is revisited with individual-level 24 h recall data. The robustness of the results is tested by comparing household- and individual-level estimates. The role of other factors that may influence dietary diversity, such as market access and agricultural technology, is also analysed.
Numerous innovation platforms have been implemented to encourage the adoption of agricultural innovations and stakeholder interactions within a value chain. Yet little research has been undertaken on the design and implementation of innovation platforms focussing on issues other than market access and aiming to encourage agro-ecological intensification.
Innovation Platforms (IPs) have become a popular vehicle in agricultural research for development (AR4D). The IP promise is that integrating scientific and local knowledge results in innovations that can have impact at scale. Many studies have uncovered how IPs work in various countries, value chains and themes. The conclusion is clear: IPs generate enthusiasm and can bring together stakeholders to effectively address specific problems and achieve ‘local’ impact.
Although much has been written on how to implement and facilitate innovation platforms efficiently, few studies support ex-ante appraisal of when and for what purpose innovation platforms provide an appropriate mechanism for achieving development outcomes, and what kinds of human and financial resource investments and enabling environments are required. Without these insights, innovation platforms run the risk of being promoted as a panacea for all problems in the agricultural sector.
Rapid climatic and socio-economic changes challenge current agricultural R&D capacity. The necessary quantum leap in knowledge generation should build on the innovation capacity of farmers themselves. A novel citizen science methodology, triadic comparisons of technologies or tricot, was implemented in pilot studies in India, East Africa, and Central America. The methodology involves distributing a pool of agricultural technologies in different combinations of three to individual farmers who observe these technologies under farm conditions and compare their performance.
The innovation system perspective acknowledges the contributions made by all stakeholders involved in knowledge development, dissemination and appropriation. According to the specific agricultural production system, farmers adopt innovations, modify them or innovate on their own. This paper examines the role of farmers' experiments and innovations in Cuba's agricultural innovation system (AIS), identifies knowledge exchange encounters and describes some strategies implemented to institutionalize farmers' experiments and innovations.
Con el fin de brindar experiencias, el presente trabajo se desarrolló en fincas de campesinos de La Palma, Pinar del Río, y Urbano Noris, Holguín, dos localidades fuertemente afectadas por la sequía y salinidad en nuestro país. En ambas comunidades, los productores e investigadores han experimentado diferentes alternativas, las cuales transcurren desde sistemas simples para la captura de agua de lluvia hasta la introducción de diversidad en distintos cultivos y nuevas variedades tolerantes a las condiciones locales.
Con el objetivo de crear un marco de colaboración que favorezca la gestión de la información que los miembros de la red generan y ponerla al servicio de la comunidad científica, además de permitir el intercambio de conocimientos y la cooperación como método de trabajo para que en el futuro surjan acciones conjuntas, se desarrolló y publicó desde el año 2008 el Sitio Web de la “Red Temática Manejo de la Simbiosis Micorrízica en Agrosistemas” que divulga y promueve el trabajo investigativo realizado por los miembros de esta red y sus principales resultados.
